FEEDING MECHANISM FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 345,953, dated July 20, 1886.

In the accompanying drawings, A B C are The arrangement of the wheels F G on the shaft E and the wheels a Z) on the shafts IV is represented in detail, Fig. 6, and can be readily comprehended by the skillful machinist.

In the construction of the machine it will readily be comprehended that the lift and sidemoving mechanism T is arranged on each side of the rolls, and they work simultaneously with each other both in vertical and side movements. The frame-work of the lifts should be provided with guides, as indicated at an in Fig. 3.

If it should be desirable to have the wheels F G and a b separated from each other in their movements on their shafts,loel -levers, as indicated at ,0 in Fig. 4, may beemployed, which arrangement of lock-levers is well understood by the skillful machinist; but preference is given to that arrangement and construct-ion indicated in Fig. 6.

1 2 refer to parallel bars, a pair of which are arranged at each side of the rolls.

One of the bars3 of the roll-carriage,form ing part of the laterally-shifting mechanism, rests upon the guides presented by the bars 1 2. The pinion R, above the pinion Q, is also keyed upon its shaft so as to movelaterally thereon, the said shaft being designated by the figure 4, and bearing at its ends in short standards, (shown in dotted lines, Fig. 3,) which are attached to the ends of the guide-bar 1. The racks hare secured at one end to the underside of the barS, and are extended horizontally and supported upon the geanwheels For the sake of clearness, the extended lateral portion of the shaft 4- has been omitted from Fig. 1; but the operation of parts in immediate relation therewith is such that as,

the carriage and roller-frame T move laterally under the power imparted to the racks the keyed wheels I, Q, and It also move therewith, but are continuously driven by the power received from the shaft N.

The chains] are connected at their extremities to a horizontal bar, 5, said connection being made outside of the limit of the lateral movement of the carriage T. Inasmuch as the inner end of said carriage only rests upon said bar 5, the carriage can move freely and laterally relative thereto. IVhen power is imparted to the chains j j, the bars 5 5 will be elevated and correspondingly elevate the inner end of each carriage T, the shaft 4 constituting a pivotal bearing for each carriage.

The operation of the machine hereinbefore described is as follows: The iron to be rolled is placed upon the lifts T, and the rollers S will carry it forward on one of the lifts to the rolls, and from the rolls on the other lift, and the operator by the movements of levers 1) dz (2 ships into gear the wheels FG and a b and the couplings m x and y, which will bring the other portion of the mechanism into motion, thereby moving the lifts T laterally, which may be moved to the right orleft, at the will of the operator, through the medium of the lever (1, whereby the wheels (0 Z) are brought into gear with the wheels 6, the wheel a causing the mechanism that operates the lifts T to move in one direction sidewise and the wheel b to move them in a different direction. If the operator desires to elevate the lifts, it may be accomplished thr ugh the medium of a chain, j, orsteam-eylinders and pistons, as hereinbefore mentioned, it being readily understood that thelifts T should be elevated or depressed in harmony with the ordinary manipulation of the iron in the process of rolling, and with a corresponding lateral motion.

Having thus dcscribed'our improvement, what we claim as of our invention is- 1. The combiuatiomin a rolling-mill,ofrolls, a carriage, a roller-frame therefor for feeding to the rolls and pivoted at its outer end, means for laterally shifting said carriage and roller frame, and devices for inclining said rollerframe on its pivot,so as to vary the feed of the latter to the rolls, substantially as set forth.

2. The eombinatiomin arolling-mill, of carriages arranged at each side and provided with roller-frames pivoted at their outerends, means for laterally shifting said carriages, and devices for simultaneouslyinclining said roller-frames, substantially as set forth.

3. The combination, in a rollingmill, of rolls, a pivoted carriage, a bar, 5, pulleys k is, chains connected to said bar and passing over said pulleys, and means for operating said chains to elevate the bar 5, substantially as set forth.

In testimony whereof we have hereunto set our hands this 10th day of June, A. D. 1884.
